Abstract: 272,909. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Travers, B. A.). June 16, 1926, [Convention date]. Regulating transformers.-A transformer comprising a primary 2 and a tapped secondary 3 supplies a load circuit 13. A motor 36 is used to rotate the tap changing drum 4 for the winding 3 and at the same time rotates another drum 61 for a tapped auto-transformer 58, associated with protective apparatus thereby connecting the protective apparatus so that it is always energized by the true ratio of input and output energy. The winding 3 comprises a pair of parallel windings, 9, 11 connected through an auto-balance transformer 12 with the circuit 13, and when the drum 4 rotates the tapping points on the windings 9, 11 are changed alternately.

Abstract: 844,157. Hooks. ALEXANDRA TOWING CO. Ltd. May 24, 1957 [May 24, 1956], No. 16040/56. Class 89(2) In a tripping mechanism for a tow hook, a hook 10 pivoted at 13 between side plates 16 is interconnected to a tripping lever 12 pivoted at 15 between the side plates 16 by a link 11 similarly pivoted at 15, the hook having a swivel block 17 engaging in a recess 18 in the link 11 which is formed with a flat surface 20 engaging a swivel block 19 on the tripping lever 12, the surface 20 being at right angles to the line joining the pivots of the swivel block 19 and the lever 12 so that the towing force on the hook does not produce a turning moment on the tripping lever. A spring pressed locking bolt 23 in the tripping lever 12 engages a recess 25 in the link 11 and may be released by pulling a wire 28 attached to the outer end of a bell crank lever 26 connected to the bolt 23, continued pulling rotating the tripping lever to free the block 19 from the surface 20 whereupon the link 20 turns and frees the towing hook. The hook is so shaped that if the inclination of the tow rope increases, the rope will slip off the hook before the direction of the force it exerts passes through the pivot of. the hook. In a form described in the Provisional Specification the link turns in the opposite direction to free the hook and the recess in it faces the hook.

Title: Rotating Cylinder Internal COmbustion Engines
Inventor: FRANKE WALTER
IPC: F02B57/00
Filed: 1967-04-08
Abstract: 1,177,106. Rotary cylinder engines. W. FRANKE. April 8, 1967, No.16186/67. Heading F1B. In a rotating cylinder engine having a piston 3 reciprocating in a bore 9 of a block 2 rotating in a stationery casing 1, cooling air from a blower enters at 14, passes through orifice 15 into the hollow piston and then flows into chamber 17 from which it enters the cylinder combustion spaces through ports 25, 26 to form the charge. Ignition occurs when orifice 12 or 13 passes igniter hole 8 and combustion gases are exhausted through port 5. Sealing blocks 10, 11, at the ends of the cylinder are formed of carbon, aluminium alloy, cast bronze or cast iron. The piston rotates about an axis eccentric of the axis of rotation of the cylinder block. The piston carries pins 37, 38 Fig.3 projecting through slots 41, 42, Fig.4 in the block and carrying shoes 39, 40, embracing an eccentrically arranged ball race 54. The cylinder block is formed with cooling fins (21, Fig. 1, not shown). Cooling air is supported by a blower (59, Fig. 6, not shown) and fuel may be supplied through pipe (60). A thermostat in the space 17 controls a discharge valve 28 for the cooling air; at a predetermined temperature the thermostat opens valve 28 and increases the blower output to prevent overheating.

May 26, 1930, No. 16187. Convention date, May 25, 1929. [Class 37.] The moving system is carried by a supporting unit 11 which is removable from the top of the cell box 10 containing the damping liquid. The vibrator element 11 consists of a circular head 12 and a frame 17 carrying the parallel conductors 14, mirror 15, and tensio.ning means 16. The frame 17 is shaped externally to fit into a tubular guide 18 cut away in front to accommodate the movable element. The guide 18 is carried by a circular support 19, the upper face of which is recessed to take the head 12 of the vibrator element. The support 19 is revolubly mounted in a plate 22 and on a portion of its periphery has teeth engaging a pinion 21 by which it may be adjusted about its axis, which passes through the mirror 15 thereby permitting this to be adjusted about its vertical axis between the pole-pieces 24. The plate 22 is hinged at 23 to the top plate of the cell box and can be tilted by means of a cam 30 so that the conductors 14 and mirror 15 are moved backwards clear of the pole-pieces. The cam 30 also withdraws a pin 26 which normally prevents withdrawal of the vibrator unit. The unit may then be withdrawn without the moving system coming into contact with any obstruction. A pin 34 at the lower end of the frame 17 engages a corresponding hole in the bottom of the guide 18 so as to position the vibrator element when inserted into the guide. In a modification the guide for the vibrator element is moved straight back from the front of the cell box instead of being tilted.

Abstract: 220,283. Geffcken, R. H. H., Richter, R. H., Wetzel, M. H., and Wetzel, M. K. Aug. 6, 1923, [Convention date]. Locating conductors.-In method of locating conductors or magnetizable bodies by the change of frequency produced in an oscillating circuit, two or more oscillating systems are coupled together and adjusted so that by the variation of the natural frequency of one of the oscillating systems, considerable variations occur in the coupling frequency or the frequency of one of the oscillations present. Fig. 3 shows an arrangement in which an oscillating system containing an inductance 8 and a condenser 9 is excited by a thermionic valve 10 and is coupled through a variable coupling 13 to a second oscillating circuit containing an inductance 6 and condenser 7. The curve 14 Fig. 2, shows the relation between the wave length and the inductance in the circuit 8, 9, the curve 15 showing the same relation for the circuit 6, 7. The opposed portions of the curves 14, 15 may be utilized by arranging the inductances 6, 8 in the form of a cross and allowing them to rotate about the axis of intersection. On the approach of a conductor an increase in frequency alternates with a decrease. Alternatively two arrangements as shown in Fig. 3, together forming an interference tone, are employed. in one of which the inductance 8, and m the other the inductance 6, are exposed to the action of a conductor. The frequency of one generator is increased and of the other decreased on approach of a conductor, causing a charge in the interference tone. The exposed coils may form a cross. In a modification two excited systems may be coupled together. The coupling may be inductive, conductive, capacitive, resistance, or a combination of these. Specification 147,440 is referred to.
